Case Report: A 72-year-old male patient was referred to the Department of Stomatology presenting a proliferative nodular lesion in the anterior region of the mandible involving the anterior teeth. The clinical examination revealed anterior teeth affected by periodontal disease, suggesting the nodular cession hyperplastic reaction.

Mechanical Ventilation and Cytopathological Changes in the Oral Mucosa.

Background: The oral mucosa is an important defense barrier to penetration of microorganisms. Thus, changes in the oral epithelium might indicate risk for infection in intensive care patients receiving mechanical ventilation.

Objective: To evaluate the oral mucosa of intensive care patients who did or did not receive mechanical ventilation by using liquid-base exfoliative cytology.

Host and clinical aspects in patients with benign migratory glossitis.

Objective: Investigate the association of clinical, cytological and genetic characteristics with benign migratory glossitis (BMG).

Study Design: Sample consisted of 175 patients, 44 with BMG and 131 control patients. Clinical examination and DMFT index were assessed.

Evaluation of cellular proliferative activity in patients with oral lichen planus and hepatitis C through AgNOR method.

The objective of this study was to evaluate the cellular proliferative potential of oral lichen planus (OLP) lesions from patients without hepatitis C virus (HCV) by means of AgNOR method, as well as the cellular proliferative potential of the normal oral mucosa from patients with HCV, treated or untreated by interferon and ribavirin. A cross-sectional study was developed to investigate four groups: 10 HCV+ patients without clinical signs of OLP who had never been treated for HCV infection - Group 1; 10 HCV+ patients that were under interferon and ribavirin treatment - Group 2; 15 patients with reticular OLP lesions histopathologically confirmed, without HCV - Group 3; and 15 blood donors without HCV infection and no clinical signs of OLP GROUP 4 Control Group. The cytological material of all groups was collected by the liquid-based cytology technique.

The uniqueness of the human dentition as forensic evidence: a systematic review on the technological methodology.

The uniqueness of human dentition is routinely approached as identification evidence in forensic odontology. Specifically in bitemark and human identification cases, positive identifications are obtained under the hypothesis that two individuals do not have the same dental features. The present study compiles methodological information from articles on the uniqueness of human dentition to support investigations into the mentioned hypothesis.

Position of the greater palatine foramen: an anatomical study through cone beam computed tomography images.

Purpose: The block anesthesia of the greater palatine foramen (GPF) is largely used in minor oral surgeries, periodontics and general dentistry. Furthermore, the area of the GPF serves as a donor of soft tissue graft. So, the aim of this study was to evaluate the position and characteristics of the GPF in Brazilian patients using cone beam computed tomography (CBCT) providing anatomical information for the greater palatine nerve block anesthesia and indicate site to collect palatal donor tissue.

Applicability of Willems model for dental age estimations in Brazilian children.

Several studies described tooth development as a reliable pathway for age estimations. Depending on the considered life span, the dental age indicators vary. In children, combinations of developing teeth provide the best information about age.

Orthodontic treatment of a patient with dentin dysplasia type I.

Dentin dysplasia is a genetic disorder of the teeth that affects the dentin and the pulp. Type I is sometimes called "rootless teeth," because of the loss of organization of the root dentin, which often leads to a shortened root length. The purpose of this article was to present a rare clinical case of a girl who was diagnosed with dentin dysplasia type I when she was referred for an orthodontic evaluation.

Assessment of variations of the mandibular canal through cone beam computed tomography.

The neurovascular bundle may be vulnerable during surgical procedures involving the mandible, especially when anatomical variations are present. Increased demand of implant surgeries, wider availability of three-dimensional exams, and lack of clear definitions in the literature indicate that features of anatomical variations should be revisited. The objective of the study was to evaluate features of anatomical variations related to mandibular canal (MC), such as bifid canals, anterior loop of mental nerve, and corticalization of MC.

Characterisation of additional mental foramina through cone beam computed tomography.

Variations in jaw bone neurovascularisation must be identified to decrease the potential risk for haemorrhages and neural disturbances during surgical procedures such as implant placement and orthognatic surgeries. The aim of this study is to characterise additional mental foramina (AMF) through cone beam computed tomography (CBCT) images, by describing their frequency, size, location and direction of their associated bony canals, as well as to assess their corresponding ipsilateral and contralateral mental foramina (MF). CBCT images from 285 patients were analysed.
